.DETACHABLE HEAD FOR BRICK OR TILE MACHINES.

SPECIFICATION forming part of Letters Patent 413,834, dated Octber29, 1889. Application filed November 3, 1888. Serial No. 290,056. (No model.)

To all whom it may concern:

Be it known that we, EDMUND RoTHwELL, NAPOLEON L. DARGIS, and ALBERT ANDREWS,

citizens of the United States, residing at Lit-.

tle Falls, in the county of Morrison and State of Minnesota, have invented a new and useful Improvement in Detachable Head for Brick or Tile Machines, of which the following is a specification.

Our invention relates to improvements in detachable head for brick or tile machines, in which the head-plate is secured to the body of the machine by a pivot-bar and.lugs and press-bar and eyes, and in which the die or mold plate is hinged to the face of the head.

The object of our invention is to secure the ready and rapid means of removing the head of the machine and of cleaning the die or mold plate from roots and other obstructions. We attain'this object by the device shown in the accompanying drawings,in which- Figure 1 is a View of the outer face of the head anddie or mold plate. Fig. 2 is a view of the press-bar. Fig. 3 is'a sectional view of the body of the machine and the detachable head.

Similar letters refer to si milar parts throughout the several views.

On the plate B vof the body of the brick or tile machine B we make holes to accommodate the eyebolts L .and L and K and K.

the end of the press-bar G.

These eyebolts are provided on the inner surface of the head with a lug g and h. The

outer end of the eyebolt K and K is provided with a rectangular mortise, which holds The outer end of the eyebolt L-and L is provided with a round hole, which accommodates the end of the hinge-bar M. We then fit to the plate B a second plate A, which is made to conform to the depression in the outer face of the plate B ,and has a perforation of hole in the center for the accommodation of the die or mold plate 0. On the outer and lower face of this plate A is secured the hinge-bar M, which is provided with rounded ends that project through the round holes in the eyebolts L and L. In the center line above and below, and at right angles on the sides of the plate B, we make four holes and top themv with a thread, to which we fit the set-screws X, turned bya handle. In the center of the plate A we make an opening and fit to it the die or mold plate 0. Across the inner mouth of the die or mold plate 0 we fit two knives or cutters, set vertically, to divide the column of clay into three (3) parts. On the lower side of the die or mold plate 0 we make the lugs a and a, which fit into and hinge with lugs 19 and b on the plate B by the rod d. On the sides of the die or mold plate 0 we make a flange or rim 0. This die or mold plate is rectangular in section and has the inner surface squared. Above the die-or mold plate O we make a pivoted lever E with a shorter arm D and a longer arm, the lever E being secured by the pivot f to the plate A at such a point that the short arm D of the lever will rest upon the die or mold plate 0 and against the flange c and bind it tightly. The longer arm of the lever E is bent at an angle and tends to one side. Near the outer margin of the plate A it is held in a notch 0. At a point remote from the hinge-bar M we put the eyebolts K and K, and into the mortise of the eyebolts K and K fit the ends of the pressbar G. The press-bar we make of a straight bar of metal widened in the middle and perforated by a hole fitted with a thread and accommodating a screw 1, which is turned by the handle H.

Having thus described the parts of our invention, we now proceed to explain the method of using the same.

\Vhen the parts are put together and the lever E thrown up so that the long arm rests in the notch O, the ends of the press-bar G are thrust through the mortises in the eyebolts K and K, and the handleH of the screw- 1 turned so as to tighten up the screw which binds the plate A firmly against the plate B of the machine B. As it sometimes happens that the plate A in coming up does not register or match exactly the end of the auger or piston in the body B, in this case the setscrews X are used to set up the plate A. When any obstruction occurs or it is desired to take off the head or plate A, it is only necessary to make a few turns of the screw I to loosen the press-bar G and slip it out of the plate the operation is reversed and the lever E restored to the notch O.

Ve are aware that the device consisting of a faceplate or head that may be removed is not new, and We do not, therefore, lay claim to such in the broad sense; but

What we do claim, and desire to secure by Letters Patent of the United States, is

In a brick or tile machine, the combination of a body B, plate B, set-screws X, and eyebolts L and L K and K, combined with the hinge-bar M, plate A, press-bar G, screw I, and handle H, all substantially as and for the purpose set forth and described.
